The Shapley SuperclusterLooking from Earth, the main clusters of the Centaurus supercluster (with yellow labels) lie directly in front of the Shapley supercluster. Between the Centaurus and Shapley superclusters, at a distance of about 500 million light years, is another small supercluster (with green labels). At a distance of 650 million light years is a massive concentration of major galaxy clusters (marked with blue labels) This is the Shapley supercluster first noticed by Harlow Shapley in 1930. The diagram above left is a plan view, with the Milky Way at the bottom left. The upper right hand hand image is the view from Earth towards Shapley.
